[PATCH liburing v1 1/7] liburing.h: Export `__io_uring_flush_sq()` function

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

clang says:

  queue.c:204:10: error: no previous prototype for function \
  '__io_uring_flush_sq' [-Werror,-Wmissing-prototypes] \
  unsigned __io_uring_flush_sq(struct io_uring *ring)
           ^
  queue.c:204:1: note: declare 'static' if the function is not intended \
  to be used outside of this translation unit \
  unsigned __io_uring_flush_sq(struct io_uring *ring)

This function is used by test/iopoll.c, therefore, it can't be static.
Export it.
